LISBON, Portugal (AP) — Hurricane Lorenzo powered across the Atlantic Ocean on Wednesday, lashing the Azores with heavy rains, powerful winds and high waves and significantly damaging one island’s main port.

The Azores Civil Protection Agency said the Category 2 hurricane felled trees and power lines as it passed just west of the Portuguese island chain.

Hurricanes the size of Lorenzo are rare so far north and east in the Atlantic basin. Lorenzo is producing huge swells across the North Atlantic as it moves northeast toward Ireland and the United Kingdom and weakens to a Category 1 hurricane.

The U.S. National Hurricane Center in Miami said swells generated by Lorenzo were being felt along the eastern coasts of the United States and Canada, in the Bahamas, and in parts of western Europe. The swells are bringing life-threatening surf and rip currents, it warned.

It said Lorenzo is “likely be a fairly vigorous cyclone” when it reaches Ireland late Thursday.

The U.K. Met Office forecast “very strong winds and heavy rain” for western areas of the country on Thursday and Friday.

The Portuguese weather agency said the most affected islands in the Azores archipelago were Flores and Corvo, where weather stations reported gusts of up to 163 kph (101 mph) _ lower than forecast as Lorenzo lost some power over cooler water.

Portuguese Prime Minister Antonio Costa said he had spoken to Azores officials at daybreak and the hurricane risk had peaked without major incident.

“Fortunately, everything indicates that things have not turned out as badly as we feared,” Costa told reporters in Lisbon.

Azores Civil Protection Agency chief Carlos Neves said 39 people were safely evacuated and no injuries were reported. He said the main port on the island of Flores had suffered “grave damage” as part of the dock, the port’s building and some cargo containers had been “swallowed” by the sea.
